Heat exchanger Vertical expander

The Heat exchanger Vertical expander machine adopts vertical layout, and the equipment is composed of base, guide post, oil cylinder, hydraulic station, workpiece clamping device, electric control box, etc.

Vertical tube expander is a kind of special equipment for processing fin heat exchanger.

Its working principle is to insert the expanding rod and expanding head into the copper tube of the heat exchanger through hydraulic transmission to make the copper tube plastic deformation, so as to make the copper tube and fin contact closely.

The operating system of the equipment is controlled by touch screen, which has the advantages of compact structure, intuitive and convenient operation, high degree of automation and long service life.

The expansion rod fixing device of the equipment adopts groove and retaining plate positioning, and the expansion rod adopts cylinder positioning. Its advantages are that the expansion rod is easy to load and unload, and the retaining plate ensures the unity and accuracy of the expansion rod in work.

The expansion rod and expansion head of the equipment adopt advanced heat treatment method, which makes the expansion rod not only have a certain hardness, but also increase its willfulness, thus increasing their service life. The device adopts the door type loading and unloading mode, which is easy to operate, reduces the manual labor of workers, and is a product that users can choose.
